Do you mean where it has actions of "Add value to column" and "Remove value from column", adding other choices into that? It isn't a feature I would personally use but there is never any harm in floating ideas here to see if other users want the same thing to justify the effort. If I was going to support that I would likely have to support other device options as well, such as "Send to device", "Remove from device", "Add to reading list" and "Remove from reading list".
